EINAR LESCHBRANDT, OF PHILADELPHIA, PENNSYLVANIA.

PHOTOGRAPHIG CAMERA.

To all whom it may concern:

Be it known that I, EINAR LnsoHBRANn'r, a resident of the city ofPhiladelphia, county of Philadelphia, State of Pennsylvania, haveinvented certain new and useful Improvements in Photographic Cameras, ofwhich the following is a specification.

My invention relates to improvements in photographic cameras and theobject of my invention is to furnish in connectionawith a camera a meanswhereby a person without special skill or practice can print in type asuitable title or inscription upon the film or plate.

In carrying out my invention I furnish a means whereby the title can beplaced symmetrically appearing upon the negative, a means whereby theletters may be evenly spaced and alined, and a means whereby. theoperator may bring any particular letter rapidly to its appointedposition.

My invention is illustrated in the accompanying drawings in whichsimilar numerals' of reference indicate similar parts throughout theseveral views and in which- Figures 1 and 2, are, respectively, a topplan and a side elevation of a camera case embodying my improvements:

Fig. 19, a plan Referring to Figs. 3, 4 and 5, 1 are parallel strips ofmetal secured upon opposite sides of partof camera showing the curtainand shield of Figs. 17 and 18 in position for operation. a

to the inner partof the camera back or lid 2. 3, best shown in Fig. 5,is a plate of metal secured to the under sides of strips 1, there beingthus formeda support for, and means to guide the movement, of, thecharacter bearing curtain 5 and the shield 4, these being situatedbetween the plate 3 and camera back 2. V As I prefer to print theinscription flexible, such as celluloid for instance, and

the characters thereon may beeither opaque on transparent ground or'viceversa, forming, in either case, light pervious patterns. These are bestseen inFig- 15 where 5 is a curtain having the patterns or charactersthereon disposed in a series of straight and parallel rows, there beingin each row a set of the letters which constitute the alphabet, and alsofigures and punctuation 'marks.

The purpose of this curtain, hereinafter called the type curtain orsimply the cur tain, is to form photographic images of its separatecharacters upon the film or plate carried by the camera when light isadmitted through them. In the particular form of my invention asdescribed in this application, which form may be considerably modifiedwithout departingfromthe spirit of my invention, it is necessary duringthe selective compounding of characters that only one single characteron thetype curtain pass light at one time as the apparatus is sodesigned that the title or inscription is printed letter by letter whenexposure is made partly by means of the slot 6, Figs. 3, 4, 7 9 and 10and partly by the spacing shield 4, which is of opaque or red materialfurnished with a diagonal line of transparent squares or windows afar-64best showif in Fig. 1a, which lies over the type curtain, each squarebeing adapted to pass light at one time to but one of the characters ofthe typecurtain, the opaque part of the shield blanketing all othercharacters. i

Vhile I have shown a diagonal or oblique row of transparent openings itwill be un derstood that if these openings were merged into one so as toform a long, transparent, obliquely placed slot it would act in the samemanner, andI make no distinction between a row of openings as shown inthe spacing shield 4:, Figs. 3 and 14, and a single opening,successively used, as shown in the modlfication.

The parts l5 have one of their longis tudinal edges smooth and the otherfurnished with teeth or notches, for instance ,the right hand side ofcurtain 5 and the left hand side of shield 4: are notched and thesenotches are adapted to'be engaged by toothed.

wheels 78 respectively. These wheels are shown in Figs. 3, 6, 11, and13. By turning wheel 7 type curtain 5 may be moved longitudinally and byturning wheel 8 the spacing shield 4 may be similarly moved. f

Fig. 6 is an exaggerated sectional View on line CC of Fig. 3 showing athin strip of metal 9 separating the spacing shield from the typecurtain so that each may properly engage with its toothed actuatingwheel. 10 is a thin piece of metal beneath the type curtain 5,11 apartition separating pieces 9 and 10 at one end and engaging the smoothside of the type curtain to hold its toothed side in engagement withteeth of wheel 7. 12 a similar partition separating plate9 and cameraback 2 and serving the same purpose with respect to shield 4 as doespiece 11 to curtain 5.

13-14 are lugs on plates 9 and 10 which engage opposite sides of thetype curtain near its toothed edge to hold the teeth in properengagement with the. teeth of wheel 7 Similar lugs 15 on back 2 andplate 9 serve the same purpose for the toothed edge of shield 4.

The wheel 7 is fitted with a shaft 16 which carries a milled wheel 17and the shaft 16 of wheel 8 carries a wheel 18, the wheels 17- 18 beingupon the outside of the camera back 2, and by means of these wheels thetoothed wheels 78 may be turned by hand to slide the parts 15 forward orbackward. lVhen'moved forwardtheir forward ends enter the curved chamberat the end of the camera and will thereby be bent around the cartridgeor film roll 19, Figs. 4, 9 and 10, thus being taken care of. By furtherref: erence to Figs. 9 and 4; it will be seen that the curtain andshield pass over a table 22,

formed by the lower end of the head frame 21 of the camera, over which,also, passes the photographic film 20. The frame 21-21 forms the openingthrough which light is admitted from the regular lens of the camera inthe photographing of pictorial views on the film, the latter being astrip of the usual length to permit the exposure of a series of views."

Above the table 22 the back 2 of the camera carries a tongue 23, whichmay be cut from the metal of the back as shown In Fig. 7, which has asort of T shape in the free end or head of which is formed a slot 6.

against the film 20, a condition desirable for sharp printing, thespacing shield cutting out the entire row of characters which is inregister with the slot except the one character below the particulartransparent window a of the shield which also registers with the slot. 1

By using the expression registering with the slot or similar expressionin this specification and claims, I mean when referring to letters, thatthey record with the slot or are placed opposite same so that light canpass through to printthem on the light sensitive sheet. 7 V

A photographic camera constructed according to my invention may be aplateholder or other camera or holder for photographic material, but theinvention is particularly adapted for its embodiment in the film-roll orfolding type of camera shown. and the printing of letters does notdepend on whether or not the usual bellows extension at the front,fragmentarily shown in Fig. 4, is in position of contraction orexpansion. g i

The pitch of the notches or teeth upon the edges of parts 45 are equal.to the height of the windows a in the shield a so that every time thelatter is moved one tooth successive windows a are brought to the vanceda toothwill bring a new row of characters along. the slot 6, one ofthese characters being in register with the window a in the spacingshield that is beneath slot 6. The parts 4l5 are independently,

movable and any desired character upon the type curtain may be broughtin register with the window a on the shield that is beof the adjacentrow to the right, and so on,

exposing the film or other sensitized element to thesemasterletters soas to form words in definite relation with the previously photographedpicture, the selective adjustment being made more easy by thearrangement whereby succeeding letters in any one longitudinal, rowstand above one anotherin the regular a-b-c order of alphabeticprogression, as they may then pass the slot in a sequence alwaysfamiliar to an operator.

I have used in this specification and in the claims such terms as slot,elongated aperture, elongated opening, as more or less synonymous terms,meaning to cover thereby any lineal opening format-ion. A lineallyformed passage or a lineally formed opening are terms also intended tosignify a lineal opening formation. g

It is desirable that the type curtain and shield be so arranged as toexposetheir characters and windows correctly below slot 6 and for thispurpose I use springs 24 to engage the teeth of wheels 7 8 in such amanner as to stop these wheels in proper position to register theletterscarried by the curtain and the windows carried by the shield.

Directly above slot 6 in tongue 23 is a similar slot 26 in a cap 27which is carried by the back 2. The cap 27 carries a shutter 25adaptedto be passed between slots 26 and 6 so that no light may pass throughthe latter. This shutter is U shaped one leg closing slot 26 the otherslot 6 as shown in Figs. 9 and 10. Near one end the shutter has anextension 28, best shown in Fig. 13, which is furnished with a slot 29and a raised lip or,

pin 30 and a spring tongue 31. In the back of the camera is carried apin 32 which enters slot 29 in projection 28 and serves as a guide forthis projection in its movements. 33 is a lever pivoted at 34: andfurnished at its free end with a slot 35 to receive the lip or pin 30carried by projection 28. 36 is a push button projecting up through thetop of case 27 the lower end of which carries a wedge 37, shown bestperhaps in Figs. 9 and .tion 28 and shutter 25 with it 10, which bearsagainst the side of lever 33 and which upon being depressed will movethe free end of the lever 33, Fig. 13, to

the left which will in turn move the projecopening slots 26 and 6 to thelight. I

Attached to the button 36 is a stiff piece of metal 38, Figs. 3 and6,the ends of which are bent down so as to engage the sides of the tongue23 when the button 36 is depressed and move the free end of thls tonguedown to the position shown in the enlarged view F 10 in order to holdthe shieldand type curtain and the film 20 close together and againstthe table 22. This is desirable in order that the characters on the typecurtain maybe printed upon the film without blurring.

Then the pressure of the finger against the button 36 is relieved thebutton will be raised owing to the elasticity oftongue 23 and a spring39 operating against the outer side of lever 33 will return this lever,the projection'28, and the shutter 25 to their first position shown inFig. 9 in which the shutter closes the openings 26 and 6.

In addition to operating the shutter 25 and connected parts as describedabove, pushlng button 36 accomplishes still another function, namely themovement of the shield one notch so that the next-window on this shieldwill be brought, to the next proper space to the right to expose thenext succeeding letter of the title to the action of the light. v a

This movement of the shield is performed by the return movement of thespring tongue 25 inward, engages'a tooth on wheel 18 and moves thiswheel so that the wheel 8, which actuates the shield, will be moved adistance snfiicient to move the window in the shield 4; that is beneathslot 6 away from this slot and the next adjacent window into registerwith this slot. The spring tongue 31 has to be moved both backward andforward in contact with wheel 18. At the shutters closing movement thetongue actuates the wheel. At its opening movement it slides past thewheel and at the same time provision must be made to turn the wheel 18by hand either backward or forward without its being e 31 which, whenthe wedge on button 36 is released, moves with the lever 33 and shutterlocked by the spring tongue, and this is ac- I complished as follows,references being had to Figs. 11, 12 and 13 A spring detent 24: engagingthe teeth of moved in either direction. When the shutter 25 is moved tothe left to open slots26-6 the spring tongue takes the position shown inFig. 12. The part 41 of the tongue has now passed tooth 18 and the cut40 in the tongue is opposite this tooth which passes through it as shownin Fig. 12. When, now, the button 36 is released and the shutter 25 ismoved to the right to close slots 26-6 as previously described the outerend of the cut out part 40 of the tongue 31 will engage the tooth 18 andwill move the wheel 18 the space of one tooth in the direction of thearrows Figs. 11 and 12. As the wheel 18 turns the next tooth 18 willcome up against the flat end 41 of tongue 31 and in its circular swingwill move the tongue out to the position shown in Fig. 11. 6

By reference to Figs. 1 and 6 it will be seen that the wheels 17-18project slightly outside the cap 27, the sides of the cap beingappropriately slotted for this purpose, so that these wheels can beturned by the finger in order to set the spacing shield and the typecurtain.

It is necessary that the operator should know what character he placesbefore the exposure slots 26-6 and for this purpose I place in the back2 of the camera a slot 42, Fig. 1, through which may be seen the extreme right hand row of characters on the type curtain 5. As the shieldpreferably lies over the type curtain and is mostly.

opaque I leave a transparent band 43 on the right hand side ofthiS'shield, as shown in Fig. 14, through which this row of charactersmay be seen. For convenience sake the slot 42 in some distances awayfrom the exposure slots 26-6 and it is therefore necessary that imilarcharacters in the row reserved for sight be correspondingly away fromsimilar rows reserved for photographic exposure. In other words when acertain character is SQBIT'RlQ the center of slot 42 a row consisting ofsimilar characters are in register with slots 26-6.

There is also placed in the camera back 2 aslot 44 through which theshield may be seen and by having the latter appropriately marked, asindicated by the numerals 2-4-8, &-c., Fig. 14, the operator can arrangethe shield so as to place a title perfectly central under thephotographic image. If there be eight letters in the title he would movethe shield until the figure 8 appears beneath slot 44. This will bring awindow a in the shield 4 into register with slots 26-6 four spaces tothe left of the center of these slots which is the correct position forthe beginning of a title of eight characters. It will be obvious thatvmarks other than numerals may be placed upon the shield 4 for assistancein centrally locating a title.

- One end of the parts 4-5 is bound with a metal bead 45 which, whendrawn up to the teeth of wheels 7-8, prevents the wheels from furtherturning as the head has no notch 'into which a (tooth can enter thusserving as a stop without ripping the teeth on parts 4-5: This stop isalso utilized to obtain the space between words, for when curtain 5isthus positioned no row of letters is before the exposure slots 26-6and when the button 36 is depressed the spacing shield 4 passes one ofits successivepositions without the film or with a letter. i

In order that the camera may be perfectly light proof the cut outportion of the back forming the part of the tongue 23 which is exteriorto the cap 27 will be covered by the usual leather covering of thecamera. and in the interior of the cap one may, if necessary, place apiece of opaque paper or other covering on the bottom of the cham herand upon which the shutter can glide.

To operate the device the wheel 18 is turned by the finger until theproper numeral or mark is seen through opening 44 in the camera back toindicate the position of shield 4 for the first letter of the title.Holding the camera in the left hand with the thumb resting over button36, the right hand'is run along the wheel 17 until the first letterof'the title appears at the center of slot 42.. (This center isindicated in any suitable manner). This action has placed in registerwith slots 26-6 a row of letters corresponding to the letter seenthrough slot 42. The button 36 is now pressed and the plate beingimpressed shutter 25 moved to uncover slots 26-6 and 100 light is passedthrough the window of shield 4 that is in register with slots 26-6 andthe image of the character beneath this window is photographed on thefilm. All

of the other characters of the line 01": char- 10 acterg being beneaththe opaque part of shield 4 are not photographed.

The first character of the title having been exposed to light the button36 is re leased and on the return, or closing move- 11 ment of theshutter 25 the tongue 31 turns the wheel 18 the space of one tooth andthe shield is advanced one stepbringing the next window therein intoposition beneath the slots 26-6 to expose the second charac- 115 ter ofthe title to light. The operator now moves wheel 17 until thesecondcharacter of the title is seen through slot 42 when the button 36is again pressed and so on until all of the characters of the title have120 been exposed.

Rolls of film, as now made, are furnished with a backing strip of opaquepaper, and for my purpose this paper would have openings or windows atregular intervals to per- 125 mit access to the film to title each view.In Fig. 8, 47 is such a strip of paper, the openings 46 being cuttherein at intervals substantially equal to the length of the openingformed bythe frame 21-21. There is 130 one opening 46 for each of theregular sequentlal exposure numerals, the latter being, as seen in Fig.8, placed near one edge of the paper together with T. F. marks, meaningtitle in foreground. The object of the latter is to assure correct adjustment for printing the titles within the pictures, being appropriatelyplaced therefor in the paper. The film carrying spools at opposite endsof the camera operate in the usual manner, the film together with thebacking or cover 47 being wound up on spool 19 when the spool is rotatedby hand from the exterior of the camera, and when so wound, theappearance of an exposure numeral beneath the red glass 48 in the cameraback denotes that an opening 46 has come opposite the slot 6, as well asthat a fresh, unexposed, film area has come into position for Viewexposure. By printing the title while the exposure gnumeral is beneaththe glass, the title will be placed below the picture, and by adjustingthe film and cover to bring the nearest T. F. mark beneath the glassafter the view exposure is made, the title may be printed on theforeground at a proper distance from the bottom of the view.

In the herein described construction of the camera, it is important thatthe film shall be shielded from light during the exposure of theletters, and, included in the provision of means for this purpose, Ihave shown an arrangement of the letter printing aperture, or slot, withrespect to the film whereby the former is so situated that light cannotspread within the camera beyond the desired area. Especially when ahighly sensitized film is used in the camera is it important that lightadmitted for the pho-.

tographing of characters shall not spread beyond the des red area,wh1ch,however, may vary somewhat in extent, depending on whet-her it isopacity or transparency' which predominates in the character curtain.In. the latter case a larger film portion opposite the slot is liable tobe exposed, but, in either case, those film portions farther away fromthe slot will be shielded, such as for instance the film area opposed tothe opening or passage formed by the filmmasking frame through which thepictorial proper agreement of picture boundary and i the typed line onthe part of those elements producing them, and toward the even spacingof each character of the line away from the boundary; 7 and the disposalof these elements adjacent the fixed path of film travel insures thesame effect for the se lective printing inside or outside the bound-Fig. 18,1ies on top of band 50 and has two I windows a-a. Both bands areadapted to glide in an appropriate groove forth and back independentlyof each other. When one of the letters of the upper row of letters onband 50 is seen through window a the corresponding letter onthe lowerrow of letters on the band will bein register with thewindow a and underorover a slot 6 carried by the camera. The admission of light to theslot 6 and to thephotographic film or plate is controlled by a shutter52 which normallycovers the whole slot 6 but which can be drawn awayfrom the slot, being guided in guides H-I. Whena title is to beimpressedon the negative the operator sets the band 51 so that thewindow a is placed in the desired position for the first letter of thetitle. He then moves the band 50 so as to place the desired letter inregister with window a. The shutter 52, which meanwhile has beencovering the slot- 6, is now withdrawn to admit light through windows ato the letter which is photographed on the film. The shutter is nowclosed and the band 51 is drawn tobring the window a to proper positionfor the next letter. The band 50 is now moved until the next desiredletter is seen through inspection window a when the shutter 52 isoperated to admit light as before, and so on.

To facilitate the proper movement of the band 51 for spacing the lettersit, the band, may have graduation marks J and the camera may carry astationary pointer K which, with the graduation marks, will make it easyto properly move the band 51 for properly spacing the letters of atitle.

i If the operator-chooses, he can entirely} Withdraw the shutter 52 anddispense with it, in that case covering and uncovering the opening orwindow a with the finger with which he manipulates the band 51 whileforming words. on the film. The band is also adapted to be slid over tothe side so the opening may be out of register with the slot 6 in thecamera back, thereby entirely closing the slot, the band alone beingsufficient for this. It is of course equally efficacious for use inconnection with a lettercarrying element like the curtain 5.

The curtain, as well as the band, is shown as being arranged to be movedin a straight line of travel opposite a slot, but the curtain will uponmovement become deflected or bent by the sliding engagement with thecurved end portion of the casing. Nevertheless, when the path of travelof the curtain 5 is viewed as by sighting down upon Fig. 3, it will beseen that it is a straight path or line of movement, hence an expression herein referring to the path or line of movement as being straightdoes not, within the intended meaning, preclude the bending of thecharacter-carrying material as viewed in another plane.

It will be seen that I have provided a camera which, while it carries afilm-masking frame to shadow graphically define the pictorial boundaryduring view exposure, a character-printing device whereby any person,though he be unskilled in the art of writing, can print a neat line ofinscription in definite and pleasing relation with the picture boundaryas defined by the frame, particularly its lower member 22, and meanswhereby the pictorial area is held in a light excluding inclosure sothat an inscription may be printed before or after View exposure, it canalso be used to print a title directly upon a positive paper print fromany untitled negative. It is also adapted to serially identifyexposures, not merely those of a single film-roll, but progressivelythroughout a series of rolls, marking exposures in alphabetic order, autility particularly advantageous in connection with notetaking tooextensive to go on the film. To this end the curtain 5 may beappropriately adjusted each time, the slot 42 recording exteriorly theprogress in the series, and the operator may print a record as hechooses, may, for instance, keep the shield 4 withdrawn from the slot 6as its teeth or notches, leading all way out to the upper edge, permitits withdrawal, then move theshutter to print on the film at once allthe characters he has adjusted before the slot. This is advantageous asa line of them would be more conspicuous and easily observed in thedark-room during development and would show up very effectually on thenarrow margin between successive view exposures without encroaching onthe picture area.

It will be understood that the camera embodying my invention, whethersuch cam-' era is of the type shown, a plate holder, a printing frame,or other holder for photographic sensitized material, need notnecessarily be provided with all the features herein described, in orderthat the formal ture in one of its exterior walls,

ran-1,692

characters or types may be selectively adjusted and printed so as toform an inscription in relation with the picture, as the most importantpart of the photographic inscription device, when considered by itselfalone, are the types and an aperture, and by the provision of a suitableadjustive accommodation therebetween an operator is enabled toselectively print letters, figures, sequential records, etc.

While the shield a is regarded as a valuable auxiliary in connectionwith the longitudinal alphabetic rows, particularly when operating onhighly sensitized film, it will be apparent that the word-formingoperativeness of the device shown in Fig. 3 is due primarily to thelongitudinal parallel rows whereof each has letters from A to Z, theslot 6, and the adjustability of these rows across the slot for thepurpose of selection, the equidistant spacing" of these rows from leftto right determining the spacing of the letters of the printed word. Inconnection with the less sensitive photographic print paper, when thedeviceis utilized to print the title directly 011 the positive print,and as the back extends over to conceal the majority of letters, anyperson with elementary knowledge of photographic printing would be ableby appropriate hand-masking before the slot, in any convenient manner,to cause only desired letters, which he'may by sight select out of theserows, to be printed so as to form words on the paper, whereby a largepart of the result contemplated by the use of my invention may beobtained without necessarily requiring the presence of all the partsherein shown and described. And this word-forming operativeness of thedevice, even though the shield 4 be absent, may apply to the use of filmas wellas paper, for, whether film be of high or low sensitivity, theactinic value of the light transmitted through the patterns or typeswould merely depend on the light source, or on the degree of lightperviousness of the patterns, or on other conditions well known to'thoseskilled in the art.

The types or patterns being previously formed for the operators use sothat he can form a title or inscription without it being required thathe shall possess skill in shaping, letters or characters, I havesometimes in the claims designated same as formal characters or formalletters or characters, these'terms being intended to signify that thecharacters (or letters), constituting a feature of the inscriptiondevice, are produced otherwise than by the operators normally operatingsaid device.
